Description

Technical Field

[0001] The present invention relates to an oil injection device for a rod of a fitting.

Background Art

[0002] There are fittings such as doors with a Gremon lock attached. As shown in FIG. 4, the Gremon lock has a lock box 3 built into a door (not shown), as also described in the following patent document.

[0003] On one side surface of the lock box 3, a thumb turn 5 and a lever handle 7 are protruding, and these thumb turn 5 and lever handle 7 protrude on the indoor side surface of the door (not shown).

Patent Document 1

[0004] On the end face of the lock box 3, a front plate 9 that protrudes at the edge of the door is provided, and from the front plate 9, a latching trigger 11 as a first advancing / retreating rod, a roller trigger 13 as a second advancing / retreating rod, and a deadbolt 15 protrude in a freely advancing / retreating manner.

[0005] Also, an upper rod bar 16a and a lower rod bar 16b protrude from the upper end face and the lower end face of the lock box 3, and the rod bar 16a and the rod bar 16b are supported movably in the vertical direction inside the door, and claw-shaped locking portions 20 provided at the tips can advance and retreat from the upper and lower end faces of the door, and the claw-shaped locking portions 20 enter holes formed in the door frame or the floor.

[0006] The rod bar 16a and the rod bar 16b are supported inside the surface material (skin plate) 4 of the door by a plate-shaped rod guide 2 having through holes formed in a horizontal flange as shown in FIG. 5.

[0007] Also, the portion of the claw-shaped locking portion 20 is guided by a rectangular cylindrical guide 12 of the upper and lower openings inside the door and protrudes outside the door.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In the fitting having a rod as described above, the operation of the rod bar and the rod guide often becomes sluggish due to oil depletion. As a result, the operation of the lock becomes heavy, which is one of the major factors causing malfunctions of the fitting.

[0009] In the case of a fitting in which only one side of the fitting has the surface material (skin plate) 4, since it can easily interfere with the inner surface of the fitting, it is possible to lubricate the rod guide 2 and the rod bar.

[0010] However, when there are surface materials (skin plates) 4 on both sides of the fitting, it is not possible to lubricate the internal parts such as the rod guide 2 because they are covered with plates.

[0011] An object of the present invention is to solve the disadvantages of the above conventional example, and in a fitting incorporating a rod having a locking portion that can be advanced and retracted from the end face of the door at the tip, even when there are surface materials (skin plates) on both sides of the door, it is possible to easily lubricate from the outside of the door, greatly improving the maintainability of the fitting, reducing the risk of fitting failure, and improving the life of the fitting. To provide an oil injection device for the rod of the fitting.

Means for Solving the Problems

[0012] To achieve the above object, the present invention firstly provides a fitting incorporating a rod having a locking portion that can be advanced and retracted from the end face of the door at the tip, and forms a rod guide provided inside the surface material of the fitting in an oil injection box, and exposes the oil injection port to the outside of the fitting. Secondly, the oil injection port to the oil injection box is a nozzle for connecting an oil injection hose. Thirdly, an oil guiding groove is provided in the longitudinal direction in the claw-shaped locking portion at the tip of the rod bar.

[0013] According to the present invention described in claim 1, if oil is injected into the oil injection box of the rod guide provided inside the surface material of the fitting from the outside of the fitting, oil is applied to the portion where the rod bar passes through this rod guide, and the rod bar and the rod guide do not become sluggish in operation.

[0014] According to the present invention described in claim 2, the oil injection hose can be connected to the oil injection port to inject oil into the oil injection box from the outside of the fitting.

[0015] According to the present invention described in claim 3, when the fitting is opened (the rod bar is retracted), oil (grease) is extruded, and the sliding portion is filled with oil. However, by providing an oil guiding groove in the longitudinal direction in the claw-shaped locking portion at the tip of the rod bar, a certain amount of oil remains, and the oil injection effect can be maintained for a long time, and the slidability can also be improved and maintained.

Effect of the Invention

[0016] As described above, the oil injection device for the rod of the fitting of the present invention is a fitting having a rod provided with a locking portion that can be advanced and retracted from the end face of the door at the tip. Even when there are surface materials (skin plates) on both sides of the door, oil can be easily injected from the outside of the door, greatly improving the maintainability of the fitting, reducing the failure risk of the fitting, and improving the service life of the fitting.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of an oiling device for a rod of a fitting according to the present invention. In the figure, 17 of the door for attaching the Gremon tablet indicates a rod bar.

[0019] The rod bar 17 is provided with a claw-shaped locking portion 20 at its tip. This locking portion 20 has a base portion 20b formed on the claw portion 20a, and the lower end of the rod bar 17 is connected to the upper surface of the base portion 20b by welding or the like.

[0020] In the figure, 18 is a rod guide provided inside the surface material of the fitting. In the present invention, the rod guide 18 through which the rod bar 17 passes is formed as a watertight metal box made of stainless steel or the like in the oiling box 19.

[0021] The oiling box 19, which is the rod guide 18, forms holes 24 through which the rod bar 17 passes in the front and rear directions. There is a slight gap between the holes 24 and the rod bar 17 so that the oil (grease) inside the oiling box 19 oozes along the rod bar 17.

[0022] Furthermore, as shown in FIG. 5, an oil guiding groove 14 is provided in the longitudinal direction in the claw-shaped locking portion 20 at the tip of the rod bar 17. The oil guiding groove 14 is a groove formed on the side surface of the base portion 20b of the claw-shaped locking portion 20, with the lower end closed and only the upper end open halfway.

[0023] Then, the oil injection port 21 to the oiling box 19 is formed as a nozzle, and this oil injection port 21 faces the outside of the fitting.

[0024] The oil filling port 21 is formed as a nozzle for connecting a vinyl oil filling hose 23 of an oil filling device 22.

[0025] The oil filling port 21 does not need to protrude outside the door which is a fitting, and it is sufficient if it faces out from a hole formed in the surface material (skin plate) constituting the door body.

[0026] Next, the usage method will be described. Insert the oil filling hose 23 of the oil filling device 22 from the outside of the door body and connect it to the oil filling port 21, and store oil (grease) in the oil filling box 19.

[0027] The rod bar 17 penetrates into the oil filling box 19 which is the rod guide 18, and the oil in this oil box 19 is applied to the outer periphery of the rod bar 17.

[0028] Furthermore, as the rod bar 17 moves up and down, oil also adheres to the rod bar 17 even outside the rod guide 18.

[0029] In particular, when the fitting opens (the rod bar contracts), the oil (grease) is extruded, and the sliding part is filled with oil. However, a certain amount of oil remains in the oil guiding groove 14, so that the oil filling effect can be sustained for a long time, and the slidability is also improved and sustained.

[0030] In this way, oil is applied to the part where the rod bar 17 passes through this rod guide 18, and the rod bar 17 and the rod guide 18 will no longer have operational resistance.
